comnmn'n 's rorrnn AND TEEN-FILLING ATTACHMENT FOB INK BOTTLES.

Application filed March 11, 1925. Serial No. 14,712.

In order to properly fill a fountain pen it is necessary that it be dipped in a quantity of ink of such depth that the point of the pen will be completely submerged. It is therefore, customary to fill a small bottle with the ink, that is, abottle of small cross section, so that a small volume of ink will have considerable deptl But repeated filling of the pen from this small bottle frequently results in the reduction of the volume in depth to' such extent that the pen thereafter may only be fill ed with difliculty, if at all, notwithstanding that there is still quite a quantity of ink left in the bottle.

The object of my invention is to provide a device which may be briefly described as a combined-stopper and pen filling attachmentfor an ink bottle; without, of course, limiting my invention to that particular use.

In other words, the object of my invention is to provide an attachment for an ink bottle, or container, adapted to serve as a stopper for the latter, and by which is provided an auxiliary receptacle, preferably tubular, to be filled from the ink contained in the bot-- tle when the latter'is turned on its side, thereby to obtain a small volume of ink of such depth that the pen maybe properly. inserted therein for filling.

I carry my invention into practice by a stopper or'cap adapted for being inserted in, or fixed over, the mouth of the bottle, and by providing in, or in conjunction with, said stopper an elongated cavity constituting an auxiliary receptacle, preferably In the form of a hollow cylinder with the long axis of the latter disposed crosswise of the mouth of the bottle; and said auxiliary receptacle preferably being given a depth equal to the width of the bottle. In the wall section of said cavity opposite the mouth of the bottle, I provide one or more orifices so as to admit ink into the cavity from the bottle, and permit air toenter'the latter; hence when the air admitting orifice is covered further flow of ink into the auxiliary receptacle is stopped. A

My invention may be carried into practice in various ways, but the two examples therei of shown in the accompanying drawing will be a suflicient illustration of the construction and principle of operation of my invention.

In said drawings: Fig. 1 represents a cap-like'closure, or stopper, for the mouth of the bottle,

which whi ch to secure a closure is provided withv a tubular cavity, or auxiliary receptacle, communicating with the interior of the bottle through orifices provided for that purpose; e Fig. 1 shows the cap provided for closing the open end of said receptacle; and

Fig. 2 illustrates my invention as consisting of a stopperv adapted for being inserted in the neck of a bottle, and said stopper being provided with a tubular cavity or auxiliaryreceptacle, communicating with themterior of the bottle by orifices extending through the stopper.

Said Figs. 1 and 2 also illustrate the manto ner of using my invention.

' Referring first to the construction of my invention illustrated by F ig. l: 0, represents a common type of ink bottle provided with a bead at the rim of its neck. 76 lVly device consists of a tubular receptacle 6 arranged with its long axis normal to the mouth of the container; and on one side of this receptacle is provided a cap c'adapted to be fastened on said rim of the neck of 80 the bottle. t

Thereceptacle b is so proportioned as to give considerable depth to a relatively small volume of fluid.- The receptacle is preferably made'of such depth, and so arranged,

that the ends of the receptacle will approximately register with the sides of the bottle a;. in that way giving the auxiliary receptacle b a depth equal to the widthiof the bottle or container. Orifices d are provided so that the auxiliary receptacle will communicate with the interior of the bottle. The open end of the auxiliary receptacle is preferably provided with a thread 6, on

cap f; the latter being shown in Fig. 1. When the penis to be filled, the cap 7"" is removed from the auxiliary receptacle 6.

Thus, when the bottle or container (1 is turned on its side, the ink is caused to flow from the bottle or container a into the auxiliary receptacle 5; and, as apparent, even though there be only a small volume of ink 15a in the bottle, it takes only a little to fill the auxiliary receptacle 6 to such de th as to enable the dipping of the en into t e ink in the proper manner for lling, as illustrated by Fig. 1.

Since ink can flow out of the bottle when displaced b 'air admitted into the bottle 11 through sai orifices, when the liquid in the auxiliary receptacle has risen to such level -in Fig. 1. The only diflerence is that the auxiliary receptacle h is provided with a stopper 2' adapted to be inserted in. the

mouth of the neck of the bottle or container g; and the stopper i is provided with orifices or ducts functioning in the same manner as the orifices d, provided in my auxiliary freceptacle illustrated by Fig. 1.

"'It will be noted that the depth of my auxiliary receptacle, shown by Fig. 2, cor responds to the distance between the sides of .the bottle or container 9. Such propor- 'ti'oning I find convenient so that when the bottle 9 is turned on its side the auxiliary receptacle h will rest on the surface supporting the bottle.

The described details of construction of my invention, however, are merely to serve as suggestions for conveniently carrying my invention into practice.

1'; claim:

1. The combination with a fluid container,

i of a member adapted to be removably se cured to the mouth of such container and including an auxiliary fluid receptacle open at one end and closed at the other and formed for communication with the container through a fluid transferring duct and an air transferring duct, the connection between the fluid container and auxiliary receptacle permitting the :passage of the fluid from the container to the. receptacle in a predetermined position of the former and automatically cutting off such passage when the air transferring duct is sealed by the fluid in the auxiliary receptacle.

2. A pen filling attachment for a bottle, comprising a tubular container open at one end-and closed at the opposite end, means carried by the container whereby it may be removably secured to the mouth of the bottle, said means being formed to provide communication ports between the bottle and container at spaced points longitudinally of the latter, whereby on tilting the bottle fluid will be discharged through one of said ports into the container and alr admitted through the other of said ports to the bottle, the rising of the fluid in the container to a position to seal the portadmitting air to the bottle serving to prevent further flow ot' fluid to the container.

3. A en filling attachment for bottles, comprising a tubular container open at one end and closed at the other, and means for removably attaching the container to the bottle to hold the container in a position normal to the mouth of the bottle, means for permitting flow of fluid from the bottle to the container in a predetermined relative position of the parts, and means for automatically cutting off said flow to limit the height of the fluid in said container.

4. A pen filling attachment for a bottle, comprising an open mouth container of substantially uniform diameter throughout, bottle attaching means carried by the container intermediate the ends thereof, and means within the plane of the attaching means to permit interchange of fluid between the bottle and container and to revent flow from the bottle to the container at a predetermined fluid level in the container.
